      e820, efi: add ACPI 6.0 persistent memory types · ad5fb870
      Dan Williams authored 
      ACPI 6.0 formalizes e820-type-7 and efi-type-14 as persistent memory.
Mark it "reserved" and allow it to be claimed by a persistent memory
device driver.

This definition is in addition to the Linux kernel's existing type-12
definition that was recently added in support of shipping platforms with
NVDIMM support that predate ACPI 6.0 (which now classifies type-12 as
OEM reserved).

Note, /proc/iomem can be consulted for differentiating legacy
"Persistent Memory (legacy)" E820_PRAM vs standard "Persistent Memory"
E820_PMEM.

      drm: Zero out invalid vblank timestamp in drm_update_vblank_count. · fdb68e09
      Mario Kleiner authored 
      Since commit 844b03f2 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.

An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.

Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

      Pull ARM fixes from Russell King:
 "A set of ARM fixes:

   - fix an off-by-one error in the iommu DMA ops, which caused errors
     with a 4GiB size.

   - remove comments mentioning the non-existent CONFIG_CPU_ARM1020_CPU_IDLE
     macro.

   - remove useless CONFIG_CPU_ICACHE_STREAMING_DISABLE blocks, where
     this symbol never appeared in any Kconfig.

   - fix Feroceon code to cope with a previous change correctly (it
     incorrectly left an additional word in an assembly structure
     definition)

   - avoid a misleading IRQ affinity warning in the ARM PMU code for
     IRQs which are already affine to their CPUs.

   - fix the node name printed in the IRQ affinity warning"
